BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates generally to a portable mobile device accessory which functions as a mouse pad, a screen cleaning cloth, a writs rest for a keyboard, a stand and a protector for a mobile device.

2. Description of Related Art

Conventional mouse pads are too big and thick to carry with a mobile device such as a smartphone, a laptop computer or a tablet PC. Previously, some have proposed a pull out mouse pad built into a laptop. U.S. Pat. No. 7,922,141 teaches a mouse pad apparatus that removably attaches to a laptop computer via spaced apart flex clips affixed to one side of the platform border. However, the conventional mouse pads need additional apparatus to carry mouse pads. Most microfiber glasses or screen cleaners are also hard to be carried on the laptop or tablet PC because they are just plain cloths. Users need to carry them on the cases separately. The conventional gel wrist mouse pads on the market are too thick to be attached or carried on the laptop computer. Thus, mobile device accessories that can be easily carried and removably attach to a surface such as a surface of a laptop computer or a tablet PC are needed.

DETAILED DESCRIPTION

The present invention will now be described more specifically with reference to the following embodiments. It is to be noted that the following descriptions of embodiments of this invention are presented herein for purposes of illustration and description only; it is not intended to be exhaustive or to be limited to the precise form disclosed.

According to an embodiment of the present invention, a portable mobile device accessory 10 includes a first layer 11 having a polymer adhesive layer 12 as shown in FIGS. 1 and 2.

The material for the first layer 11 may be varied according to the purposes of the portable mobile device accessory. For example, if the portable mobile device accessory 10 is intended to be used for screen-cleaning, a first layer 11 may be formed of a material which can be used for screen-cleaning for a keyboard, such as microfiber. If the portable mobile device accessory 10 is intended to be used as a mouse pad, a first layer 11 may be formed of a material that has a surface enhancing the usability of a mouse such as fabric, plastics, recycled rubber tires, neoprene, silicone rubber, leather, glass, cork, wood, aluminum, stone and stainless steel, optionally with an additional layer of fabric bonded to the upper surface.

If the portable mobile device accessory 10 is intended to be used as a wrist rest for a keyboard, a first layer 11 may be further formed of a material which can be used for a wrist rest for a keyboard, such as gel (e.g., polyurethane gel covered with synthetic leatherette) or foam material.

According to an embodiment of the present invention, the first layer 11 is formed of a cloth. When the first layer 10 is formed of a cloth, the portable mobile device accessory is a multi-function accessory functioning as a mouse pad, a screen cleaning cloth and a wrist rest for a keyboard of a mobile device.

The term “mobile computer” or “mobile device” in the specification and the claim section includes, but is not limited to a laptop computer, a tablet PC, and a mobile phone.

The term “cloth” in the specification and the claim section means any material which can be used for cleaning a screen or a surface of a mobile device.

The term “detachably attached” to a surface in the specification and the claim section means that a material has a re-adherable strip of adhesive on one surface, designed for temporarily attaching a portable mobile device accessory to a certain surface.

The cloth can include, but not limited to, a microfiber.

The cloth can be die cut or cut into different sizes to be attached on anywhere on a mobile device such as a laptop computer or tablet PC

Examples of material for the liquid polymer adhesive layer 12 include polyurethane and polyester.

An exemplary method of forming the polymer adhesive layer is disclosed in U.S. Pat. No. 6,613,382 which is incorporated herein by reference.

For example, the polymer adhesive layer is formed as follows:

A liquid polymer adhesive is applied onto a surface 11A of the cloth such that the liquid polymer adhesive spreads across and covers the cloth, and the liquid polymer adhesive is allowed to polymerize. Once the liquid polymer adhesive is allowed to polymerize, it forms the polymer adhesive layer 12 which is permanently bonded with the cloth surface 11A. The polymer adhesive layer 12 provides a tacky surface 12A to the cloth. The tacky surface 12A can form a temporary, removable bond with the surface of a mobile device, and yet be readily peel-removed without harming the surface or leaving a residue. The tacky surface 12A of the polymer adhesive layer 12 can also be washed with water to remove dust and other contaminants to restore the tacky consistency of the polymer adhesive layer 12.

Since the portable mobile device accessory 10 has a tacky surface 12A, it can be attached to anywhere on a mobile device.

Since the mobile device accessories 10 are thin, the laptop computer is closed easily without removing the mobile device accessories 10.

For example, the thickness of the mobile device accessory according to an embodiment of the present invention is in the range of 0.5 mm to 5 mm, for example, 0.5 mm to 3 mm, specifically, 1 mm to 3 mm.

The portable mobile device accessory 10 can be used as a screen cleaning cloth, a mouse pad and/or a wrist rest.

To be used as a screen cleaning cloth, the portable mobile device accessory 10 detachably attached to a mobile device is peeled off from the mobile device, and the detached cloth 10 can be used for getting rid of dust or finger print on the screen.

Once it is cleaned, the portable mobile device accessory 10 can be attached to the original position or anywhere on laptop/tablet pc.

To be used as a wrist rest mouse pad, the portable mobile device accessory according to an embodiment of the present invention can be modified as shown in FIG. 3A or 3B. That is, the cloth 11 or the cloth with gel or foam may have two different thicknesses as shown in FIG. 3A. Alternatively, the polymer adhesive layer 12 may have two different thicknesses as shown in FIG. 3B. The protruded surface 11C can function as a wrist rest, and the non-protruded portion 11B can function as a mouse pad.

To be used as a wrist rest for a keyboard, a single portable mobile device accessory may be detachably attached right below a keyboard of the laptop computer. If there is a touch pad right below a keyboard, a plurality (e.g., a pair) of the mobile device accessories 10 may be detachably attached right below a keyboard of the laptop computer 31 as shown in FIG. 4.

As described above, the tacky surface of the portable mobile device accessory according to an embodiment of the present invention can be washed (for example, with water or wet-towel) to clean the tacky surface, and the cloth surface can be washed as well. Accordingly, the portable mobile device accessory can be used long without losing the tackiness.

When the mobile device accessories are positioned as shown in FIG. 4, they can function as a screen cleaning cloth, a (wrist rest) mouse pad and a wrist rest for a keyboard. However, the attached position and the number of the pieces of the portable mobile device accessories can be varied according to a user's preference. For example, the portable mobile device accessory can be attached to an area next to a touch pad of a laptop computer for a purpose of a (wrist rest) mouse pad as well as screen-cleaning

Alternatively or additionally, the portable mobile device accessory 10 can be detachably attach to an outside surface of a laptop computer 31 as shown in FIG. 5.

Likewise, when the portable mobile device accessory 10 is used for a tablet PC, it can be attached to any surface on a tablet PC. FIG. 6 shows one example of a tablet PC 32 having a portable mobile device accessory 10.

Thus, a portable mouse pad, screen cleaner and wrist rest (three-in-one) can be carried easily on a mobile device such as a laptop computer and a table PC.

Even though it is one product, it can be used as three different products at the same time.

According to another embodiment of the present invention, an accessory may include a first layer 110, for example, formed of a microfiber, .an adhesive layer 111, a second layer 112 a, 112 b, and optionally a removable layer 113, as shown in FIG. 10. The adhesive layer 111 may be, for example, formed of a double-sided adhesive tape. The second layer 112 a, 112 b may be formed of a polyethylene terephthalate (PET) layer 112 a and a polyurethane gel layer 112 b. Instead of the polyurethane gel layer 112 b, a polyester layer may be formed. Since a surface of the polyurethane gel layer 112 b is tacky, the removable layer 113 may be temporarily attached to the polyurethane gel layer 112 b. When the accessory is used as a surface cleaning cloth, a mouse pad, a wrist rest for a keyboard, a stand and/or a protector, the removable layer 113 is removed. That is, the removable layer 113 can be used as a protector for the tacky surface of the polyurethane gel layer 112 b. The removable layer 113 may be formed of, for example, polyethylene terephthalate, paper or a plastic.

According to an embodiment of the present invention, the adhesive layer 111 formed of the double-sided adhesive tape may have a thickness of 100 μm, the PET layer 112 a may have a thickness of 75 μm, the polyurethane gel layer 112 b may have a thickness of 200 μm, and the removable layer 113 formed of PET may have a thickness of 75 gm.

The PET layer 112 a and the polyurethane gel layer 112 b may be clear or transparent. Compared with the embodiment having no PET layer 112 a, the embodiment having the PET layer 112 a is more stiff or sturdy because of the PET layer 112 a so that the accessory can be used more stably. Also, when the PET layer 112 a and the polyurethane gel layer 112 b are clear, the prints on both sides of the first layer 110 can be seen.

The embodiment shown in FIG. 10 may be manufactured by attaching the PET layer 112 a and the polyurethane gel layer 112 b to each other to form the second layer, forming the second layer 112 a, 112 b on the removable layer 113, forming the adhesive layer 111 formed of the double-sided adhesive tape on the PET layer 112 a, and forming the first layer 110 on the adhesive layer 111.

The accessory according to an embodiment of the present invention can be used as a memo holder due to the tacky surface of the polyurethane gel layer.

The Polyurethane gel of the polyurethane gel layer is washable reusable.

The accessory can be used as screen/glasses cleaners to be carried on cell phones, iPads, tablet PCs, and laptops, etc.

According to another embodiment of the present invention, an accessory 70 can be used a screen cleaner as well as a stand. The accessory 70 that can be used a screen cleaning cloth may have fold lines so that it can have a T shape when it is folded according to the fold line.

For example, the fold lines may include three vertical lines 71, 72, 73 as shown in FIG. 7A. The fold line may be any line to make the screen cleaner easily folded according to the fold lines. For example, the fold lines may be lines of small slits so that the screen cleaner can be easily folded. For example, the fold line may be a portion of the screen cleaning cloth in which the thickness of the screen cleaning cloth is smaller than that of the other parts of the screen cleaner. The thinner thickness may be made when the screen cleaner is made, or by pressing the portion of the screen cleaner. Alternatively, the fold line may be made by keeping the screen cleaner folded for long so that it may have a tendency to be reverted into the folded shape when it is unfolded.

FIG. 7B illustrates how the screen cleaner can be used as a stand for supporting a mobile phone. To be used as a screen cleaning cloth, the accessory 70 detachably attached to a mobile device (S1) is peeled off from the mobile device, and the detached cloth 70 can be used for getting rid of dust or finger print on the screen. (S2)

Once it is cleaned, the accessory 70 can be attached to the original position or anywhere on laptop/tablet pc or a mobile phone.

To be used as a stand, the accessory 70 having three vertical fold lines 71, 72, 73 is folded by simply attaching the fold line 71 and the fold line 73 to make it T shape. (S3 and S4) The T-shaped accessory is placed on the lower middle part of the mobile device such as a smartphone with a push/snap. (S5 and S6)

Examples of material for the accessory include polyurethane and polyester.

According to an embodiment of the present invention, since the accessory 70 has a first surface which is to clean a surface and a second surface to which a polymer adhesive layer with a re-adherable strip of polymer adhesive designed for temporarily attaching the mobile device accessory to a surface of the mobile device, the accessory has a tacky surface so that it can be attached to anywhere on a mobile device. When the accessory loses stickiness, the dust can be washed off with water or wet-towel. (S7)

According to another embodiment of the present invention, an accessory 80 can be used as a screen cleaner as well as a stand. The accessory 80 that can be used a screen cleaning cloth may have a cut. The cut has a shape to make the portion of the accessory support a mobile device when the cut portion is raised from the other part of the accessory 80. Exemplary shapes of the cut include ∩, Λ, or
